I've observed the same thing with a variety of different configurations.
I always blamed it on some inherent inefficieny in SMTP or sendmail or
something.
That probably isn't the case, though. SMTP should be no more inefficient
that HTTP--the data transmission happens in more-or-less the same way. It
probably isn't sendmail's fault either since I've seen it with sendmail,
smail and exim at various ends of the connection.
Maybe the SMTP servers at our respective ISPs are under heavy load?
Sorry I haven't helped much, but you're at least not alone.
